Sixty steel beams from the former Sydney Monorail are now lying under a road in Norwest after being turned into a road bridge.

Removed from Pitt Street in the Sydney CBD last year the monorail beams were refurbished in a Glendenning factory and used to build a temporary road bridge at the site of the new Norwest railway station – one of eight new stations on the $8.3billion North West Rail Link (NWRL).

According to the NWRL website, ‘‘this innovative solution dramatically cut the length of time a key local road had to be closed – from around three years to just three months’’.

Original plans proposed a lengthy closure of Brookhollow Avenue at the intersection of Norwest Boulevard, so the new underground railway station could be built.

Instead, a temporary bridge was built at road level and Brookhollow Avenue was then re-opened to traffic earlier this month.

Excavation of the new station will continue under the bridge.

Brookhollow Avenue was closed for three months for the bridge to be built.
